' I aim to provide a device, one vside of which [its the shoe and the other side of which lits the sole of the foot. y

My device at the center portion is hard and rigid while the edges and especially the portion under the heel and ball of the foot are more or less flexible, which construction enables the device to accommodate itself to the motions of the foot when the'user is walking.

With these and other objects in view, my

invention consists in the novel features and manner of construction herein described and more particularly pointed out inthe appended claims.v

Reference being had to the accompanying rawings forming a part of this specification: i

Figure l is a view in perspective of my improved appliance.

Figure 2 is the bottom plan view of the same.

` Figure 3 is a view incross section, sub-y stantially on the line 3 3 Figure 1.

Figure 4 is a view in section through the device showing the mould used in forming it under pressure.

Referring to corresponding parts in the several views by the same' numerals of reference: l denotes in general the improved ap-` pliance, which is formed with the rounded portion. 2 whichits within the heel of the shoe and under the heel of the foot. EX- tending forwardly from this point on one side of the supporter, is the upwardly con- 'ver portion as shown at 3, this portion resting under inside of the arch.

Y The center part of the appliance opposite this upwardly convex portion is thickened as shown at i and is formed of two layers of leather. These layers are fastened together by means of aj large number of Closely spcedel, Shown :at 5.' The nails havea head @and are driven vf'rorrrthe Vunder i i lside of the" applianceV andclinched' on the inside. By driving the nails closely'fas'here illu strated the'v 'libre ofthe leatherz'is joompressedbetween tjh'em and the Asupporter-'at this portionis made veryrigid and perfectly retainsits shape'inruse. gThesenails, in effect,""act 'inj the lsaine manner 'as `the'strut rods of a truss and so prevent deformation of the device'bythe weight of the foot@ Erom this thickened portion, the supporter tapers to a thin edge at its forward point 7, and the whole inner surface is covered with a smooth layer of leatherindicated by 8.-

ln forming this appliance l iirst cut the leather to the proper shape and then soak the same' in water. I then scarf the edges as well as the edges of the small piece9. These two pieces are then` placed together and temporarily held with twonails while placed between .the twov sections of a mould. rlhe mould is placed in apress where it is subjected to a very great pressureso as to;

thoroughly compress the libre of theleather. The shape of the mould surfaces are'that of the finished supporter which is allowed to dry in the mould.' After thersame has dried and Vbeen removed from the forms they retain their shape while the nails are being driven into the two parts. two pieces are, thoroughly attached by the closely spaced nails, the upper and lower surfaces are smoothly finished on a sanding After the y machine and then the liningrS lis cemented in place.Y y A y The mouldy sections above referred to comprise a base section 10 whichis curved at 11 to conform to the bottom 'of the supporter, an intermediate section'l2 which is curved at 13 to give the required shape/to the upper surface of the supporter. vOne of these sections has spring clips 15' which engage the other section and hold them to getherwhile the device is drying.

The section 16, is common to all moulds and is only-used to provide a atfacewhile theV pressure isbeing placed on theparts l0and12. 'j f 1 l ln use the appliance Vis inserted Vin the shoe in the usual manner with the curved rear portion 2 in the heel and the forward edge 7 on the sole of the shoe. Then the rigid hard center portion l forms a bridge between the heel andvsole and this rigidity prevents,V it being -`wished down.

Under lthese conditions the upper snraeeforms a most eicient support for the areh of the foot.
